BD Transduction Laboratories™ Purified Mouse Anti-Lamin A/C

The nuclear envelope (NE) is a specialized extension of the ER that contains numerous pore complexes interconnected with the nuclear lamina. The nuclear lamina composes the structural framework for the NE and serves as a chromatin anchor site, thus playing a major role in interphase nuclear organization. The major component of nuclear lamina are intermediate filament-like proteins called lamins. In mammalian somatic cells, there are three major lamins, A, B1, and C, and two minor lamins, B2 and A10. A-type lamins (A, A10, and C) are encoded by a single gene and are produced by alternative splicing, while B-type lamins (B1 and B2) are encoded by separate genes. B-type lamins are found in all nucleated somatic cells, while the expression of A-type lamins are developmentally regulated. Mice lacking lamin A show no overt abnormalities until postnatal development when perturbations in nuclear envelop structure correlate with the appearance of muscular dystrophy. In addition, lamin A is mutated in lipodystrophy, a disorder characterized by reduction in subcutaneous adipose tissue. Thus, lamin A and C may be important for nuclear envelope formation during postnatal cell differentiation.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.
